UP-ENDING WASHER Warner S. Luci, Moline, 111., assignor to AmericanMachine and Metals, Inc., New York, N. Y., a

corporation of Delaware Application January 12, 1949, Serial No. 70,403r V 6 Claims.

for the work to be laundered is rotatably mounted in a shell and boththe shell and the container are movable from a horizontal washingposition t a vertical extraction position.

As is well known, the combination of a washer and an extractor in such amanner that the washing and the extracting may be carried out in thesame container by changing the position of the axis thereof has theadvantage of rendering unnecessary the transfer of the water-soakedclothes from one place of the laundry to another place, the weight ofsuch water-soaked clothes amounting in commercial washers ordinarily toseveral hundred pounds. ,7

,Such machines have not come into use because when the container ismoved to the ex;- the load is not as well distracting position, tributedas in an extractor when packed by hand. Hitherto this unbalance hascreated such excessive vibration during the extraction as to prevent theuse of such apparatus.

The invention makes it possible to extract in the same container inwhich the clothes have been washed by first reducing the amount ofunbalance by dividing the load into two lots separated by a diametralpartition in the container, then by aiding the distribution of the loadabout the axis through draining ofi the pool in which washing has takenplace'only after the container has reached extracting position,

and finally by providing a suspension that absorbs the vibration createdby the remaining unbalance.

In the preferred operation of the apparatus, the container is repeatedlymoved from one po'- sition to the other and to facilitate this the container is made to tilt about an axis that is located to one side of theextraction spindle, passing close to the center of gravity of thecontainer and its load.

An object of the invention is to provide a laundry machine of the typereferred to which has the shell and the container mounted on a laterallymovable platform which supports the shell and the cylinder both in theirhorizontal washing position and in their vertical extraction position.

Another object of the invention is to provide a laundry machine of thetype referred to having the shell and container mounted on a platformwhich, while permitted to sway freely in a horizontal plane, will not besubject to substantial vertical vibrations.

A further object of the invention is to provide a laundry machine of thetype referred to in which the platform which supports the shell and thecontainer both intheir washing position and in their extraction positionis linked to a stationary base in such a manner as to be biased toassume a specific position relative to said base from which position itwill deviate substantially in a horizontal plane only.

A further object of the invention is to provide a laundry machine of thetype referredto wherein platform is suspended from columns standing upfrom a stationary base by means of linking elements permitting aswaying-movement of the platform relative to the base and whereinrigidly connected to the platform are supporting means which support theshell and the container both in their washing position and in theirextracting position. I

A further object of the invention is to pro-'- vide a laundrymachine ofthe kind just referred to wherein the linking elements by means of whichthe platform is suspended from the columns are attached to arms whichare rigidly connected to and extend upwardly from the platform, thepoints of attachment being situated in a horizontal plane passingthrough, or close to, the center of gravity of the shell with all partssupported thereby' or thereon when the shell is moving from the washingto the extract ing position.

' A further object" of the invention is to provide a laundry machine'ofthe type'referred to wherein the shell together with the parts carriedthereby is supported in the horizontal position as well as in thevertical position on three points rigidly secured to theplatform'; twoof these three points remaining the same for both positions whereas thethird point of support, for supporting the shell when in the horizontalposition, is different from the third point of support for supportingthe shell when in the vertical position;

Another object of the invention is to provide a laundry machine of thetype referred to wherein the container is divided into separatecompartments which are accessible through doors in an endwall of thecontainer and in an end wall of the shell.

A further object of the invention is to provide hydraulically operatedmeans for opening and closing the door or doors in the end wall of theshell.

Still a further object of the invention is to provide pivotal supportsfor the shell on a horizontal axis extending to one side of the axis ofthe shell and approximately in the horizontal position but being in anineffective position for... draining when the shell is in thehorizontal" position.

Another object of the invention is to provide a brackets-"3| a cross bar32 on which the shell 23 highly economical method for-operatinga1laundry-- machine of the type wherein a container for thework to belaundered is rotatably mounted in a shell and both the shellandthecontainor. ares movable from a horizontal washing position to a vvertical extraction position. In commercial" washing it is generallynecessary to apply in succession a plurality 'tifsudstreatments and 'ofrinsin}; operations to. tne sanie lot o'f' material tojbe' cleansed.With this inyiew', the invention con templates the application Iof thesuds and rinsing treatments in such 'a: way thatthe she'll andcontai'ner are tilted" from the: horizontal washing position tothevertical extraction position each time a suds or' rinsing treatment'iscompleted and to allow the spent liquid to drain on when the shell andcontainer are the'vertica l: position.

The'cylinder-or basket Z lwithin the shell-23 comprises a perforatedsidewall as, end walls 49 and-50v andapartition wall 5!, the lattercontaining the-rotational axisof the basket soas todivide the basketvinto two semi-cylindrical compartments-52 and 53; The compartment 52-for rotation therewith. The. shaft 60 is supported in two bearings BIand 62.which are carried by a bearinghousing 63 supported on the bottom64 of the shell 23. The, basket shaft 60 ex: tends outwardly beyond thebottom 64 of the shell 23 and carries on this extended end a pulley 65which is provided with a braking surface 66 and a drive belt surface 61.A belt 68 passes over the surface 61 of the pulley 65 and over anotherpulley 69 on the driving shaft of the motor 10. The motor 10 which ismounted on the shell- 23 by means of a bracket 1! is a high speed motorfor imparting to the basket 24 the high extraction speed and it ispreferably connectable with the shaft 60 of the basket 24 bymeansproviding for either mechanical ,or electrical slip-.- page as is wellknown in the art and therefore not illustrated in the drawing.

A second motor 12 is secured to the bottom 64 of the shell 23. means of'a belt 13 a pulley 14 supported by a shaft 15 which also. carries aWorm 16. The

worm 16 engages a worm gear 11 mounted on a stub shaft 18 which issupported, by a bearing 19 carried by a bracket 80 that extendsdownwardly (as seen in Fig. 1) from the bottom 64 of the shell 23. Thestub shaft 18 is arranged coaxially with the basket shaft 60 and carriesa coupling member 8| of a clutch which is denoted as a whole by thereference numeral 82 and whose second coupling member 83 is carried bythe basket shaft Bil. The two coupling members 8| and 83 of the clutch82 may be brought in and out of engagement by' a shift lever of anydesired design, not shown. The motor 12 is provided for revolving thebasket 24 at a low speed when the machine is washing. Since it iscustomary with washing machines to carry out the washing process in sucha'manner that the cylinder containing the material to be washed isrevolved a number of times in one direction and then reversed to revolvein the opposite direction, the motor 12 is preferably designed for suchoperation. The electrical reversing controls for such a motor are wellknown in the art and are, therefore, not shown in the drawing.

On the underside of the shell 23 there are provided to the left andto-the right of the center two parallel tracks 84 and with each track.84 cooperatesa roller 85 carried by a lever 86 which is swingablymounted on a pivot 81 carried by a bracket 88 secured to the platforml2. 'Each ofthe two levers 86 has a pin 89 to which is con nectedapiston 90 moving in a cylinder 9|. The two cylinders 9 I bear againstfulcrums 92 car-.. ri'ed by the platform l2. Dashpcts comprisingcylinders 93 and pistons 94 are provided to. prevent a too violentswinging of the shell 23 about the trunnions 21'.

For the purpose of discharging liquid from the shell 23 there-may beprovided in the shell one or more discharge openings. The drawing showstwo such openings, the one being indicated at 95 and the other at 9B.The opening 95 is provided in the bottom 64 of the shell 23 at such apoint that, when the machine is in the washing position shown in Fig. 3,the opening 95 is situated near the top end of the machine, so that nodischarge will occur through that opening prior to the machine-beingturned to the exi-j traction position where the axis of the shell isvertical. The .second' discharge opening 95-, which is normally heldclosed by a valve 91 @is' arranged in the cylindrical wall of the shell23 at a point thereof which issituated in the lower;

The motor 12 drives by most region ofthe shell when theqlatter is in thewashing position of Fig. 3. Of-the two discharge. outlets 95 and 96shown one, preferably the outlet-95', may be dispensed with aswillbecome apparent later. v

The machine may be loaded either in the extraction position of Fig. 1 orin the washing position of Fig. 3. In either case the quadrant doors 34and 35 are opened by supplying fluid pressure to the hydraulic ram 41.This reveals one of the two doors 54, 51 in the end wall 50. of thebasket, 24. This door, which according to Fig. 3 happens to be the door54, is opened and half the load of clothes to be washed is placed in thecompartment 52 of the basket 24. The

door54 is then-closed and the basket is turnedfor a half turn so thatthe basket door 51 becomes aligned with the open half of the shell' 23.The door 51 is opened and the second half. of the load of clothes is,placed in the basket compartment 53. Now the basket door 51 is closedand the quadrant doors 34, 35 of the shell 23 are also closed, thelatter by operating the ram engine 41. e

Itwill be noted that the arrangement of the doors in the end walls ofthe basket and shell is advantageous whether the loading is carried out.with the axis of the washer horizontal or vertical. When the loading isdone in the horizontal position of the machine shown in Fig. 3, then thedoor which is in alignment with the opening in the shell andwallfurnishes in itsv open position a horizontal support for the clothes tobe placed in the coordinated basket compartment. On the other hand, withthe shell and basket in vertical position, it is possible to load themachine from an elevated chute or the like. After thetwo compartments52, 53 have been loaded with the clothes to be treated and the doorshave been closed as just described, water and detergent have to besupplied to create a pool of liquid in the shell 23 and the basket 24.This is being done with the shell and basket in the horizontal washingposition shown in Fig. 3, and if shell and basket are not already inthis position for the loading of the basket with the clothes, they haveto be brought into this position. This is-achieved by applying fluidpressure to the cylinders 91 so that by means of the pistons and thepins 89 the leversfifi are turned in counterclockwise directionias shownin Fig. 2). The levers 86, by means of'their rollers 85, move' the shell23and the basket 24 from the position shown in Fig. 1 through theposition shown in Fig. 2 to the position of Fig. 3. The shell 23 turns.

thereby about theaxis 29 of-the trunnions 21."

Whereas prior to the beginning of this 90' tilt of the shell 23 thebottom 64 thereof had rested on the seat 30 on the oneplatform arm 2|,atthe 'end of this movement the side .wallof the shell 23 settles downon the crossbar 32'carried-by the platform l2. However, due to themounting in the bearings 26 carried by the platform I2, the shell 23 issupported bythe platform i2 all the time, that is to say, never leavesthis platform.

When the shell is filled with water and detergent up to the desiredlevel, indicated in Fig. 3 at 98, the clutch 82 is closed and the motor12 started. As the motor l2 is of the reversing type, the basket 24 iscaused to revolve alternatinglyin one direction and the other at a lowspeed desirable for washing, such as 25 R. P. 'M; After the first sudstreatment is finished, the dirty water may be drained off through theoutlet 98 by opening the dump Valve 91. Then, asusual. washing amaze" 7*may 'be restaiitent witha iiew qiiantity or: water containing detergent,{and} after-repeating the suds treatment several times, dumping. theused washing liquid-i after each such: treatment, the clothes may berinsed for a certain; number of times with warm water.- Wlien all thesewashing and rinsing steps, whichmay include also bleaching, bluing, andsouring steps, have been carried out and the liquid has drained outthroughthe outlet opening 98, and after the clutch 6! has been opened tocut out the motor 12, the shell 23 together withthe basket 24 is, byreleasing the fluid pressure in the cylinders 9i, allowed toturn-intothevertical extraction position shownin- Fig. 1. Since the axis 29 aboutit'l iit'ali' theshell and the basket turn issituated eccentrics-11y of"the axis of the shell and basket; the-latter will tend" to assume thevertical-postt'ion' -of'Fig; 1- unde'rtheir own'wei'ght' so that thebottom E4 of the shell 23 willcome to rest on the seat 36." In thisposition ofthe shell-23 the-motor Wisstarted, throwing thebasket'" 24into extraction speed, which may be a speed of, e. g, 725 R. P, M. Afterthe extraction has led to the desired "degree of removal of the moisturecontained in the clothes; the machine is brought to a standstill'a'ndtheclothes are removed first from the one basket'compartment and then fromthe other. The removal of the clothes ispreferably carried out in thehorizontal position of the machine. If in thisposition of the machinethe shelldodrsfi-d, 35 are'openedand the basket 24 is tiirned'sothat-the partition wall extends in the horizontal plane, then theopendoor 54 or 5 1 of that particular basket compartment 52 or 53, whichhappens to-be at this time the upper half: of thebasket, serves'asan'apronwhich perinits the comfortable unloading of that particularcompartment; This compartment having been unloaded and" its door closed,thebasket is turned 180 1s'o"that the other half ofth'ebasket is on topand aligned with the shell opening" for being unloaded;

The described machine may be operated in a more advantageous mannerwhich consists in tilting the m'achine from the position of Fig; 3 tothe'po'sition shown in Fig. I each time one of missiles orrins'ing'treatments is completed, and to allow thespent washing solutionto drain off when. and only-when; the shell isin'theup-ended position ofFig; l. This-mode of operation permits the attainment of a desired"degree of. cleanliness with "fewrsuccessive suds: and rinsing treatmentsthan" the previously described method wherein allj-sudsin'g and rinsingsteps are carriedoutiprior to any extracting operation. From thefollowin example it will be seen how the two methods compare:

f Ifthedescribed machine is loaded with; say; 150 lbs; of*soiledclothes, these clothes will absorb more than twice their weightof water so that; iipo'n opening-of the drain opening 95, the clotheswill weigh more than 450 lbs. afterthe water not absorbedby the clotheshas drained oif'from the shell; Assuming that in the first sudsoperation 1 substantially all ofthe dirt loosens and goes into solution,then of the total amount of water in the container, whichcomprisesthatabsorbed' by the clothes'and that forming thepool of the level 98,only-oriequarter passes out through thevalve 91. In other: words, if thesoil" is uniformly distributed throughout the water, as muchas of'thesoil originallypresent is still present. after draining titers-the firstsudsitreatment has-been completed; shell lSfl'lOW- refilled withwashing-liquid up toztlrie'zlevei =88and;thefclothestara-suhziectedrtq'asecond:washing:operatiomwliereupomthevalve 91 is openedagain; there.will remains in; theclothes or approximately X of the. soil which wasoriginally: present. After: the. third, suds treatment,followedbydumping, thcrewill. be. left. in themateri'at to be cleansedof the: original soil and thewfourth'treatment will leave retainedintheclothes /255z0185b011t /3 of theoriginal soil.- Thuswith thiswashing method, which". is sub" stantially' the conventional method;.ordinarily five to ten-diflerentibathsxare necessary to achieve asatisfactory degreepf cleanliness. Whenthis degree of cleanlinesshasbeen. reached and the liquidhas been dumped for: the last time throughthe valve: 91; the shell 23 with the basketj-z'lis lip-ended into theposition shown in Fig. 1.. In this up-ended position the basket 2'4 isrotated'at extraction speed by the motor: '18" to I remove as much" ofthe water which was absorbed" by-the clothes asispossible.bycentrifugalextraction.

A muchgr'eater economy resultsif theillu'strated"combinedwasher-extractor; instead ofJbeing used for: thejust'd'escribed conventional wash-' ing method; isup end'ed after eachwashing oper ation for a centrifugal extraction and the extractedliquid" isdiained off each time; This method req'uires, or at leastrenders favor-able. the presenceof the outlet opening which assumes theposition shown in Fig. I at the bottom end of the shell EB'WIien-thi'sshelland the basket are rip-ended. The outlet opening; 96 is either ennanently lcept closedor'may be entirely dispensed with so that'the wasliing liquid will not leave the shell as-longas the same is inthe-horizontal washing position. Up totheti'me the shell and basketapproachtheir vertical position the clothes are still floating in a poolof liquid so'a's to be better distributed in each sectional compartmentof the basket for the following extraction operation: than theywould. beif-the liquid had been dumped while the shell and basket were still inthe horizontal position. Now; the basket 214 is rotated hymeans of themotor 'lfi'atsuch aspeed that the clothes which may have again a dryweight of lbsand" which have absorbed. at least Silo-lbs:of.liquid.,will.contain. after-the ex traction. step only 150 lbs. ofliquid. Con: sequentlypthe total weight. of" clothes plus abcurbedliquid. is 300 lbs, instead of the 450 lbs. which wouldbepresentprior tothe secondsud s treatment. according to the previously describedconventional method; In. the clothes. there will beretained'onlyapprojximately V oflthei soil origi? nally-present' as: comparedwith. the 5%. of' the original, soil" left for the second. suds,treatment when theLconV'entiOnaIimethod.is used. Prior to the thirdliquid treatment therewill' be. present, when the novel method. is used,5i{; .oi. the, original soil as comparedwith ct theoriginalsoil retainedlwhenthe previously described conventional methodiis used.Expressedin terms of percentage, this. means. that afterthree-treatments under the conventional. method thesoil contents in. theclothes, is about 45 of the. original soil whereas with. the new method.involving up-ending the washer. each time. a liquid. treatment. has beenapplied, the remaining. soil contents. is only 5%. It willbe obviousthereforeithat with. the latter method the number of. the. liquid.treatments 118C? essary for obtaining a desired. degree ofclean: linessis greatlyreduced with corresponding sanings in detergent. and othermaterials.

Whereas the final extraction"v should be carried out at the full-Speederthemotorm in order rt remove 'as much liquid as possible *prior' --tomovmediate speed. Most of the liquid-to beextracted in such anintermediate extraction step comes out 'an appreciable time before thebasket has been brought up to full speed. i

When the basket 24 is rotated, particularly at the high extractionspeed, unbalance in the load with respect to the rotational axis willcreate at the'level of the unbalance a positive force and a negativeforce of equal magnitude during each revolution. This level is at ornear the resultant center of gravity of all the rotating parts. 'As

has been described, the platform-i2 is connected to the chains l8 at theupperends of the upstanding arms 21 in a plane which at leastapproximately passes through said. center of gravity 1 of the combinedrotating parts when the machine is in the vertical position. If thepoints at which the platform is linked to its suspensions aresubstantially above or below the plane in which the forces created bythe unbalance develop then a:

moment would becreated tending tocause the platform to develop averticalcomponent of mo,- tion which would be the larger the greater thedistance of the plane in which the suspension points of the platform aresituated from the center of gravity mentioned. Such vertical componentsof motion would cause the platform to jump or jiggle on the suspensionlinkswhich would lead to a very undesirable and noisy type of vibration.Since according to the invention the center of gravity and thesuspension points of I the platform are situated in one and. the sameplane, practically no vertical vibrations will develop and theunbalances will cause no other movement of the platform l2 than swayingin the horizontal plane.
